APHIDES. APHIS 



These insects are most destructive, and there is 

 no plant they let alone. There are several species 

 of them : 



Aphis Pyraniali is an enemy to apples and 

 pears, and is of a grass-green colour. 



Aphis persiccB is dark green and devours peaches 

 and nectarines. 



ApJiis pruni infests plum trees, and is of a very 

 pale green. 



ApJiis cerasi, a black pest which infests cherries, 

 especially the Morello cherry, and attacks the 

 undersides of leaves. 



Aphis coryli, a destroyer of nuts. 



Aphis ribis and Aphis ribis nigrce^ which devote 

 themselves to red and black currants. 



Aphis fab cs, known as Black Dolphin, attacks 

 beans. 



Aphis pisi is green and affects peas. 



Aphis raphani, radish louse, females green, males 

 light red. 



Aphis lathyri, sweet pea louse, dark purple. 



Aphis dahlice, dahlia louse, amber colour. 



To prevent their appearance, about February, 

 every other year, paint every branch, with a common 

 paintbrush, with a mixture made of Scotch snuff, 

 one pound of quicklime, half a pound of lampblack, 

 one pound of soft soap, and sufficient water to 

 make to the consistency of paint. 



When the tops of beans are attacked by the 

 Black Dolphin they should be removed at once and 

 should be syringed with tobacco water or washed 

 two or three times with soapsuds.
